I have created a paper wallet and I generated the public/private keys with Ubuntu live + Electrum. Now I have 2 questions:
- In this case, can I IMPORT ( instead of SWEEP ) my keys in electrum and avoid to pay the fee each time I want to send my Bitcoin?
- I have read that if you use the IMPORT option, then when you spend a portion of the Bitcoin, then the unspent amount will go to another address. Is it true? Why? Then I have to store another pair keys for the new address?
Thanks, I am newbie ❤️
